public class LetNode extends Scope
AST node for let statements and expressions. Node type is Token.LET or Token.LETEXPR. 
 LetStatement:
     let ( VariableDeclarationList ) Block
 LetExpression:
     let ( VariableDeclarationList ) Expression
Note that standalone let-statements with no parens or body block, such as let x=6, y=7;, are represented as a VariableDeclaration node of type Token.LET, wrapped with an ExpressionStatement.

  • Method Details

    • getVariables

      public VariableDeclaration getVariables()
      Returns variable list

    • setVariables

      public void setVariables(VariableDeclaration variables)
      Sets variable list. Sets list parent to this node.
      Throws:
      IllegalArgumentException - if variables is null

    • getBody

      public AstNode getBody()
      Returns body statement or expression. Body is null if the form of the let statement is similar to a VariableDeclaration, with no curly-brace. (This form is used to define let-bound variables in the scope of the current block.)

      Returns:
      the body form

    • setBody

      public void setBody(AstNode body)
      Sets body statement or expression. Also sets the body parent to this node.
      Parameters:
      body - the body statement or expression. May be null.

    • getLp

      public int getLp()
      Returns left paren position, -1 if missing

    • setLp

      public void setLp(int lp)
      Sets left paren position

    • getRp

      public int getRp()
      Returns right paren position, -1 if missing

    • setRp

      public void setRp(int rp)
      Sets right paren position

    • setParens

      public void setParens(int lp, int rp)
      Sets both paren positions

    • toSource

      public String toSource(int depth)
      Description copied from class: AstNode
      Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

      Note: if the parser was in error-recovery mode, some AST nodes may have null children that are expected to be non-null when no errors are present. In this situation, the behavior of the toSource method is undefined: toSource implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

      Overrides:
      toSource in class Scope
      Parameters:
      depth - the current recursion depth, typically beginning at 0 when called on the root node.

    • visit

      public void visit(NodeVisitor v)
      Visits this node, the variable list, and if present, the body expression or statement.
      Overrides:
      visit in class Scope
      Parameters:
      v - the object to call with this node and its children
